Wait ... didn't this asshole learn from the last time they fought the MC to test his strength? Yeah, manga logic kicked in pretty hard and they got launched into a real life or death fight right after without a chance to recover their strength. I'm sure it worked out great last time too.
Also, as a related side note ... the guy only has access to one arm ... bruh ... you picking on a cripple. For shame. Yes, I know convenient plot device to have the MC regain some of his fighting spirit yadda yadda yadda so that he can make the final push to find Rokka.
Also also, that part with Momo reneging on her partial confession was ... *blech* ... how many tropes can you cram into one chapter. LOL. Onward to the end of the manga.
